In some important tests, signal jammer, as a powerful tool in the test, has played an important role in the test in order to ensure the fairness of the students' test. However, there will inevitably be some accidents in the use. How can we reduce the accidents.

The interference range of the signal jammer is related to the signal strength. Different types of jamming equipment can be selected according to the strength of the signal in different field environments, so as to make full use of the performance of the jammer. As for the effect of the jammer, the installation of the signal jammer will also have some impact due to the different building obstacles and wall materials compared with the site environment. To avoid unnecessary problems, install in strict accordance with the manufacturer's requirements. The surface temperature of the interferometer may rise after a long time of operation. These are normal phenomena, so don't worry about them.

Generally, the normal installation height of these small jamming signal equipment is about 2 meters, and the installation area should be as free as possible. It may be better if it is hung on the wall. In the process of use, it will not affect electronic equipment in other bands. At work, there is almost no sound, and it will not affect the students who are taking the exam, so you can use it with confidence. Use the signal jammer correctly to avoid cheating in the examination room and create a fair and just examination environment.
